MEAT-CUTTER.

SPECIFICATION forming part of Letters Patent No. 650,618, dated May 29, 1900. Appliatiougled November 3, 1899. Serial No. 735,671. (No model.)

To cz-ZZ whom t may concern:

Be it known that I, JOHN A. SANDER, a

citizen of the United States, residing at Newark, in the county of Essex and State of New 5 Jersey, have invented certain new and useful Improvements in Meat-Chopping Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as'will enable others ro skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and numerals of reference marked thereon, which form a part of this specification.

I5 This invention relates to certain improvements in that class of meat-chopping machines represented'by my prior patent, No. 249,405, issued November 8, 1881, the objects of the present invention being in general to zo provide means for more easily and eectively controlling the action and position of the vertical rotary shaft, which carries at its lower end the revolving cutters or knives, their spindles, and cooperating parts. More spe- 2 5 cie objects-are to enable the rotary shaft to be quickly thrown out of connection with the driving means and thus stopped, to provide means formoving the rotary shaft vertically while in motion, and thus changing the posi- 3o tion of the cutters with relation to their Work and-to secure means for temporarily locking the said shaft in any desired position, to enable the vertical adjustment of the rotary shaft and the lock-ing to be done in one op- 3 5 eration, and to secure other advantages and results, some of which maybe hereinafter referred to in connection with the description of the working parte.`

The invention consists in the improved 4o meat-chopping machine and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

45 Referring to the accompanying drawings,

in which like letters and numerals of reference indicate corresponding parts in each of the` several views, Figure 1 is a perspective view of my improved machine complete., Fig.

5o 2 is a central sectional view taken through the vertical rotary shaft, its controlling-lever,

yed to receive motion from the horizontal shaft c through cooperating bevel-gears e f. Fast and loose pulleys g g2 and a belt-shifter h 65 are provided at the opposite or rear end of the horizontal shaft c, by means of which power to drive said shaft is obtained in any usual manner. 'I he middle portion of this shaft c carries a worm z', which meshes into 7c' a Worm-Wheel j', fast on the upper end of a doWnwardly-extendin g shaftj,which imparts, through gearing z7'2 at-its lower end, a slow rotary movement to the meat-block la in any Well-known manner. Said block 7c is of or- 75 dinary construction, provided with a peripheral liange or rim la', and eccentrically pivoted with respect to the vertical rotary shaft d,

as is common. The lower end of said shaft d reaches to a point adjacent to the upper sur- 8o face ofthe meat-block, and to said lower end of the shaft is fixed a cross-frame Z, carrying the pivotal knives or cutters Z' and a hood or guard Z2, as'has been usual heretofore.

It will be understood that the knives Z', 85 carried by the shaft d, cooperate with the block 7c to secure a chopping of the meat or the like, and it is inthe means next to be described for controlling the rotation and position of the shaftdthat the present invention 9o particularly inheres.

At a point just above the lower bearing m of the shaft d in the frame b I place upon said shaft a loose collar 2, carrying the gearwheel f, which intermeshes with the coper- 95 ating gear-wheel e on the horizontal drivingshaft c. The upper end of said collar is formed into a clutch member adapted to engage with a correspondingly-formed coperating member 8, firmly fixed upon the shaft d roo Vat a higher point by means of a set-screw 3 1 or equivalent means.

vin' rige.

said sleeve to be held against longitudinal' movement away from the clutch member 3. The bearing m2, through which the sleeve 4 extends, is slotted at the front and provided with a rectangular longitudinal extension or enlargement 6, and on the corresponding side of the sleeve 4 is formed arack 41, with teeth,

42, which projects into the chamber vor space 6. Said rack 41 and rack-chamber 6,aside from their primary purpose hereinafter set forth, serve to key the sleeve 4 to the bearing m2 and prevent rotation with the shaft d.

The front wall of the rack-chamber 6 is verticallyslotted, as at 7, and parallel ears 8 8 project forwardly on either side of said slot. Between said ears is pivoted the disk-like head 9 of the controlling-lever, said head presenting at its inner side a segmental toothed portion 91, engaging the rack 41, and at the opposite outer side providing a socket 92 to receive the handle-rod 10, provided at its outer end with a handle 11. By operating said controlling-lever either up or down in a vertical plane it will be understood that the toothed end 91, intermeshingwith the rack 41 on the sleeve 4, which sleeve is longitudinally xed on the rotary shaft 4 between the collar 5 and clutch member 3, forces said rotary shaft either downwardly or upwardly without interfering with its freedom to rotate.

The clutch members 2 3 are preferably formed with long engaging jaws, so that consderable vertical movement of the shaft CZ is allowed without disengaging the clutchmem-v bers. This permits the cutters at the lower end of the shaft to be adjusted to positions atv dierent distances from the block. EX- treme upward movement of the shaft d by the controlling-lever, however, draws the upper clutch member 3 away fromthe lower member and permits the gear-wheel j to rotate idly on the shaft, as will be understood. This construction enables the cutters to be stopped without shifting the belt and thus stopping the entire machine, so that the block k may continue to rotate while the cutters are stationary.

The collars 5, sleeve 4, and clutch member 3 can be fixed at any point on the shaft d by the set-screws 51 51 or equivalent means if a greater change of position of the cutters relative to the block is required than is given by the controlling-lever. g

Y To enable the controlling-lever, and thus the rotary shaft, to be fixed temporarily in any of its various positions, I place upon the handle-rod 10 a sleeve 12, loosely inclosing said rod and abutting at its ou ter end against the handle piece 11, which handlepiece screws upon the'end of the rod 10, as shown y To the inner end of the sleeve l2 is attached, by screwing or the like, a forked brake or clamping-piece 13, centrally and longitudinally perforated to slide upon the rod 10 and having its two prongs 131 131 lying one each side of the head 9 and shaped at their extremities to fit against the projecting ears 8 8. Thus by screwing the handle-piece 11 onto the rod 10 when in engagement with the sleeve 12 the clamping-piece 13 is forced against the ears 8 3 and the controlling-lever clamped against pivotal movement.

By having the handle work upon the rod 10 byv a quick-acting screw-thread it will be seen that bygrasping said handle in one hand the controlling-levermay be given a pivotal movement to adjust the rotary shaft d and then by a twist of the hand locked in its new position. Y

Various unimportantchanges maybe made from the exact construction which I have described without departing from the spirit or scope of the invention, and I do not wish to be understood as limiting myself by the positive descriptive terms employed except as the state of the art may require.

Having thus described thc inveution,.what I claim as new is 1. In a meat-choppingmachine, the combination of a block, a horizontal driving-shaft, a vertical rotary shaft having cutters at its lower end, a clutch member loose on said vertical shaft and` carrying a gear-wheel inter meshing withl another gear-wheel on the driv ing-shaft, a clutch member, and a collar rotating with the shaft, a non-rotating sleeve arranged upon the shaft between said fixed collar and clutch member, and means for raising and lowering said sleeve, substantially as set forth.

2. In a meat-chopping maehine,the combination with a driving-shaft, of a vertical shaft carrying cutters atitslower end, a clutch member loose on said vertical shaft and carrying a gear-wheel intermeshing with another gear-wheel upon the said driving-shaft, a cooperating clutch member fast on the shaft, a sleeve loose upon the shaft and keyed in its bearing or box, and having rack-teeth at one side, means for preventing longitudinal movement of said sleeve independent of the shaft, and a pivoted controlling-lever having asegmental pinion at the end engaging said rack on the sleeve, substantially as set forth;

3. In a meat-choppingmachine, the combination with suitable bearings, of a vertical rotary shaft carrying cutters at its lower end, a clutch member loose on said shaft and provided with means for receiving power from any suitable source, a cooperating clutch member fast on the shaft, a non-rotary sleeve, held against longitudinal movement on said shaft, said sleeve lying in one of the shaftbearings and having a rack projecting into a groove or recess in said bearing, anda pivotedrlever having at its end teeth engaging said rack, substantially as set forth.

9. The combination With a controlling-lever pivoted in a suitable support and having a threaded shank, of a sleeve longitudinally movable on said shank and having its inner end adapted to engage the fixed support of the lever and a handled nut screwing on said shank to force the sleeve into clamping engagement, substantially as set forth.

10. The combination with a pivoted controlling-lever having a handle adapted to rotate, of a clamping member sliding longitudinally upon said lever and adapted to be forced against the fulcrumal bearings of the lever by a rotary movement of said handle, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 26th day of JOHN A. SANDER,

October, 1899.
